Description

Technical Field

[0001] This invention relates to the field of temperature measuring instrument technology, specifically to a measuring instrument for measuring temperature. Background Technology

[0002] Temperature, as one of the most fundamental and core parameters in physical quantities, is crucial for determining the accuracy of process control, product quality, and the reliability of experimental data. Different scenarios present significantly different performance requirements for temperature measuring instruments.

[0003] For example, CN222212019U discloses a measuring instrument for measuring temperature, including an instrument body, a battery compartment for storing a battery inside the instrument body, and a threaded groove on the inner wall of the battery compartment; a sealing element, a threaded protrusion adapted to the threaded groove, the threaded protrusion sliding along the threaded groove, the sealing element being rotatably connected to the instrument body and used to seal the first opening of the battery compartment.

[0004] However, existing temperature measuring instruments have limited functionality. Contact instruments cannot perform non-contact temperature measurement, and non-contact instruments cannot detect gas temperature. Multiple devices need to be stacked for measurement in multiple scenarios, making it impossible to measure temperature across different types. Furthermore, most instruments have fixed structures or require manual adjustment, making it impossible to achieve automated multi-dimensional adjustment of horizontal, angle, and height, resulting in low efficiency for multi-position temperature measurement. Summary of the Invention

[0007] Preferably, the support frame includes a support plate, a guide rail, a first limit sensor, a second limit sensor, and a base. The first limit sensor and the second limit sensor are respectively installed at both ends of the support plate. The guide rail is fixedly connected to the upper outer wall of the support plate. The deflection mechanism is movably connected to the outer wall of the guide rail. The base is fixedly connected to the bottom surface of the support plate.

[0008] Preferably, the moving mechanism includes a traction plate and an electric cylinder, one end of the traction plate is fixedly connected to the deflection mechanism, and the end of the telescopic rod of the electric cylinder is fixedly connected to the other end of the traction plate.

[0009] Preferably, the deflection mechanism includes a mounting plate, a servo motor, and a pulley transmission assembly. The mounting plate is movably connected to the outer wall of the guide rail via a slider. The servo motor is mounted on the back of the mounting plate, and the output shaft of the servo motor is connected to the lifting mechanism via the pulley transmission assembly.

[0010] Preferably, the lifting mechanism includes a fixed frame, a drive shaft, a first support rod, a second support rod, and a pressure sensor. The drive shaft is fixedly connected to the side wall of the fixed frame, and the end of the drive shaft is rotatably connected to the outer wall of the mounting plate. Both the first and second support rods are fixedly connected to the bottom surface of the fixed frame. Two pressure sensors are provided, and the two pressure sensors are respectively installed at the bottom ends of the first and second support rods.

[0011] Preferably, the lifting mechanism further includes a second servo motor, a lifting plate, a guide rod, and a lead screw. The second servo motor is installed on the bottom surface of the fixed frame, the lifting plate is located below the second servo motor, the top end of the guide rod passes through the outer wall of the lifting plate and is fixedly connected to the bottom surface of the fixed frame, the top end of the lead screw is fixedly connected to the output shaft end of the second servo motor, the lifting plate is threaded onto the outer wall of the lead screw, and pressure plates are fixedly connected to both sides of the lifting plate.

[0012] Preferably, the bottom of the gas thermometer is fixedly connected to an air inlet pipe, the side wall of the gas thermometer is fixedly connected to an air outlet pipe, the gas thermometer has a flow guide groove inside, and a temperature sensing resistor is fixedly installed on the inner top surface of the flow guide groove.

[0013] Preferably, an infrared emitting module is fixedly connected to the bottom surface of the infrared thermometer, and a camera module is provided on one side of the infrared emitting module, with the camera module installed on the bottom surface of the infrared thermometer.

[0014] Preferably, the supporting mechanism includes a carrying plate, a sleeve plate, and a locking bolt. The sleeve plate is fixedly connected to the side wall of the carrying plate and sleeved with the outer wall of the support plate. The locking bolt is threaded through and connected to the outer wall of the sleeve plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, a temperature measuring mechanism integrates three core components: a platinum resistance thermometer, a gas thermometer, and an infrared thermometer. This allows for solid contact temperature measurement, gas medium temperature measurement, and non-contact temperature measurement, breaking through the limitations of traditional single temperature measuring instruments. The temperature measuring mode can be flexibly switched according to the state of the object being measured. At the same time, four electric cylinders are independently driven by a controller, which can control the lifting and lowering of the platinum resistance thermometer, gas thermometer, and infrared thermometer, and optimize the data of the signal processor. This balances the flexibility and accuracy of temperature measurement and is suitable for diverse industrial or laboratory temperature measurement scenarios.

[0016] 2. In this invention, the position of the temperature measuring mechanism is adjusted in the horizontal direction by a moving mechanism, which can cover the measured points at different horizontal positions. The servo motor of the deflection mechanism drives the lifting mechanism to rotate around the transmission shaft through the pulley transmission assembly, thereby driving the temperature measuring mechanism to achieve angle deflection adjustment. When the object being measured is an inclined surface, the deflection angle of the temperature measuring mechanism can be adjusted by the servo motor to ensure that the temperature measuring element is perpendicular or directly opposite to the measured surface, thereby improving the accuracy of temperature measurement.

[0017] 3. In this invention, the servo motor 2 drives the lead screw to rotate, which in turn drives the connecting plate and the temperature measuring mechanism to move up and down as a whole, accurately adjusting the vertical distance between the temperature measuring element and the object being measured. The pressure sensors at the bottom of the support rods 1 and 2 provide limit protection for contact temperature measurement, preventing the temperature measuring element from being damaged due to excessive pressure.

[0018] 4. In this invention, the original signals of the three temperature measuring elements are filtered, linearly corrected and error compensated by the signal processor to reduce the impact of environmental interference on the data. The camera module at the bottom of the infrared thermometer captures the image of the measured area in real time and transmits it to the display. The operator can accurately align the measured point through the image, which solves the deviation problem caused by blind alignment in traditional infrared temperature measurement and improves the accuracy of non-contact temperature measurement.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Refer to Figure 1 - Figure 7 As shown: A temperature measuring instrument includes a support frame 1, a supporting mechanism 2 movably mounted at the bottom of the support frame 1, a moving mechanism 3 mounted at the top of the support frame 1, a deflection mechanism 4 mounted on the upper outer wall of the support frame 1, a lifting mechanism 5 mounted at the output end of the deflection mechanism 4, a temperature measuring mechanism 6 mounted on one side of the lifting mechanism 5, and a display 7 mounted on one side of the deflection mechanism 4. The temperature measuring mechanism 6 includes a connecting plate 61, a platinum resistance thermometer 62, a gas thermometer 63, an infrared thermometer 64, a signal processor 65, a second electric cylinder 66, a support column 67, and a controller 68. The support column 67 is fixedly connected to the top surface of the connecting plate 61. Four second electric cylinders 66 are provided and mounted on the outer wall of the support column 67. The controller 68 is mounted on the upper outer wall of the second electric cylinder 66. The signal processor 65 is fixedly mounted on the top surface of the support column 67. The platinum resistance thermometer 62, the gas thermometer 63, and the infrared thermometer 64 are all located below the connecting plate 61 and fixedly connected to the bottom end of the telescopic rod of the second electric cylinder 66.

[0023] In this embodiment, the platinum resistance thermometer 62 achieves contact-type precision temperature measurement based on high-precision resistance, suitable for stable low- and medium-temperature scenarios. The gas thermometer 63 can collect temperature data for gaseous media or sealed environments, while the infrared thermometer 64 achieves non-contact temperature measurement, suitable for high-temperature, high-risk, or inconvenient-to-contact objects. The combination of these three devices covers contact and non-contact measurement needs in multiple scenarios, including solids and gases. The four electric cylinders 66 are independently driven by the controller 68, which can control the raising and lowering of the platinum resistance thermometer 62, gas thermometer 63, and infrared thermometer 64 respectively. When contact temperature measurement is required, the electric cylinders 66... The corresponding temperature measuring element is pushed down to contact the object being measured. When non-contact temperature measurement is required, only the infrared thermometer 64 needs to be lowered to avoid mutual interference between different temperature measuring elements. The signal processor 65 receives the original signals from the three temperature measuring elements, and transmits the data to the display 7 after filtering, linear correction, and error compensation to realize the visualization of temperature measurement data. This device breaks through the limitation of a single temperature measurement method and can flexibly switch the temperature measurement mode according to the state of the object being measured. At the same time, through the precise control of the electric cylinder 66 and the data optimization of the signal processor 65, it takes into account both the flexibility and accuracy of temperature measurement and is suitable for diverse industrial or laboratory temperature measurement scenarios.

[0024] Example 2: Figure 1 - Figure 3 As shown, the support frame 1 includes a support plate 11, a guide rail 12, a first limit sensor 13, a second limit sensor 14, and a base 15. The first limit sensor 13 and the second limit sensor 14 are respectively installed at both ends of the support plate 11. The guide rail 12 is fixedly connected to the upper outer wall of the support plate 11. The deflection mechanism 4 is movably connected to the outer wall of the guide rail 12. The base 15 is fixedly connected to the bottom surface of the support plate 11. The moving mechanism 3 includes a pulling plate 31 and an electric cylinder 32. One end of the pulling plate 31 is fixedly connected to the deflection mechanism 4. The end of the telescopic rod of the electric cylinder 32 is fixedly connected to the other end of the pulling plate 31. The deflection mechanism 4 includes a mounting plate 41, a servo motor 42, and a pulley transmission assembly 43. The mounting plate 41 is movably connected to the outer wall of the guide rail 12 through a slider. The servo motor 42 is installed on the back of the mounting plate 41. The output shaft end of the servo motor 42 is connected to the lifting mechanism 5 through the pulley transmission assembly 43.

[0025] In this embodiment, limit sensor 13 and limit sensor 14 are respectively installed at both ends of the support plate 11. When the deflection mechanism 4 approaches the end under the drive of the moving mechanism 3, the sensor triggers a signal and stops the electric cylinder 32 from moving to avoid the deflection mechanism 4 from overtraveling and impacting. The electric cylinder 32 of the moving mechanism 3 drives the deflection mechanism 4 to move horizontally along the guide rail 12 through the pull plate 31, thereby adjusting the position of the temperature measuring mechanism 6 in the horizontal direction and covering the measured points at different horizontal positions. The servo motor 42 of the deflection mechanism 4 drives the lifting mechanism 5 to rotate around the transmission shaft 52 through the pulley transmission assembly 43, thereby driving the temperature measuring mechanism 6 to achieve an angle deflection within the range of 0-90°. When the measured object is an inclined surface, the deflection angle of the temperature measuring mechanism 6 can be adjusted by the servo motor 42 to ensure that the temperature measuring element is perpendicular or directly opposite to the measured surface, thereby improving the accuracy of temperature measurement.

[0026] Example 3: According to Figure 3 - Figure 5 As shown, the lifting mechanism 5 includes a fixed frame 51, a drive shaft 52, a first support rod 53, a second support rod 54, and a pressure sensor 55. The drive shaft 52 is fixedly connected to the side wall of the fixed frame 51, and the end of the drive shaft 52 is rotatably connected to the outer wall of the mounting plate 41. The first support rod 53 and the second support rod 54 are both fixedly connected to the bottom surface of the fixed frame 51. Two pressure sensors 55 are provided, and the two pressure sensors 55 are respectively installed at the bottom ends of the first support rod 53 and the second support rod 54. The lifting mechanism 5 also includes a second servo motor 56, a lifting plate 57, a guide rod 58, and a lead screw 59. The second servo motor 56 is installed on the bottom surface of the fixed frame 51, and the lifting plate 57 is located below the second servo motor 56. The top end of the guide rod 58 passes through the outer wall of the lifting plate 57 and is fixedly connected to the bottom surface of the fixed frame 51. The top end of the lead screw 59 is fixedly connected to the output shaft end of the second servo motor 56. The lifting plate 57 is threaded onto the outer wall of the lead screw 59, and pressure plates 571 are fixedly connected to both sides of the lifting plate 57.

[0027] In this embodiment, servo motor 56 drives lead screw 59 to rotate. Since lifting plate 57 is threadedly connected to lead screw 59 and limited by guide rod 58, the rotation of lead screw 59 is converted into vertical lifting of lifting plate 57 along guide rod 58, thereby driving connecting plate 61 and temperature measuring mechanism 6 to move up and down as a whole, accurately adjusting the vertical distance between temperature measuring element and the object being measured. The pressure sensor 55 at the bottom of support rod 53 and support rod 54 provides protection for contact temperature measurement. When lifting plate 57 drives temperature measuring mechanism 6 to move down, if the lower pressure sensor 55 contacts pressure plate 571 first, the sensor feeds back a signal to controller 68, immediately stopping servo motor 56 to avoid damage to temperature measuring element due to excessive pressure.

[0028] Example 4: According to Figure 6 and Figure 7As shown, the bottom of the gas thermometer 63 is fixedly connected to an air inlet pipe 632, and the side wall of the gas thermometer 63 is fixedly connected to an air outlet pipe 631. The gas thermometer 63 has a flow guide groove 633 inside, and a temperature sensing resistor 634 is fixedly installed on the inner top surface of the flow guide groove 633. The bottom surface of the infrared thermometer 64 is fixedly connected to an infrared emitting module 641. A camera module 642 is provided on one side of the infrared emitting module 641 and is installed on the bottom surface of the infrared thermometer 64. The supporting mechanism 2 includes a carrying plate 21, a sleeve plate 22 and a locking bolt 23. The sleeve plate 22 is fixedly connected to the side wall of the carrying plate 21 and sleeved with the outer wall of the support plate 11. The locking bolt 23 is threaded through and connected to the outer wall of the sleeve plate 22.

[0029] In this embodiment, the air inlet pipe 632 is used to access the gas to be measured. The gas flows uniformly through the guide groove 633 and the temperature sensing resistor 634 to ensure that the temperature sensing resistor 634 fully contacts the gas and collects temperature data. The air outlet pipe 631 discharges the gas after it has passed through, forming a closed-loop process of air inlet, temperature measurement and exhaust, avoiding temperature measurement errors caused by gas stagnation. The infrared emitting module 641 at the bottom of the infrared thermometer 64 is responsible for emitting and receiving infrared radiation. The camera module 642 captures images of the measured area in real time and transmits them to the display 7. The operator can accurately align the measured point through the image, solving the problem of blind alignment in traditional infrared temperature measurement and improving the accuracy of non-contact temperature measurement. The carrier plate 21 of the support mechanism 2 is used to place the object to be measured. The sleeve plate 22 is sleeved with the support plate 11. The position of the sleeve plate 22 can be fixed by rotating the locking bolt 23. According to the height of the object to be measured, the position of the sleeve plate 22 on the support plate 11 can be adjusted up and down to adjust the height of the carrier plate 21.

[0030] The usage and working principle of this device are as follows: When using it, if the object to be measured is a small solid, place it on the carrier plate 21, loosen the locking bolt 23, move the sleeve plate 22 up and down until the center of the object to be measured is roughly aligned with the temperature measuring mechanism 6, and tighten the locking bolt 23 to fix it; if the object to be measured is a gas, connect the gas pipeline to the inlet pipe 632 and outlet pipe 631 of the gas thermometer 63 to ensure smooth gas flow. Start the electric cylinder 32 of the moving mechanism 3, which drives the deflection mechanism 4 to move horizontally along the guide rail 12 via the pull plate 31. Combined with the prompts of limit sensor 13 and limit sensor 24, the temperature measuring mechanism 6 is moved directly above the measuring point. Start the servo motor 42 of the deflection mechanism 4, which drives the lifting mechanism 5 to deflect via the pulley transmission assembly 43. Combined with the image on the display 7, the angle of the temperature measuring mechanism 6 is adjusted to face the measuring point. Contact temperature measurement: The controller 68 activates the corresponding electric cylinder 66, pushing the platinum resistance thermometer 62 downward. Simultaneously, the servo motor 56 activates the lifting plate 57 downward until the platinum resistance thermometer 62 contacts the object being measured. The signal processor 65 processes the data and displays the temperature on the display 7. Non-contact temperature measurement: Only the electric cylinder 66 corresponding to the infrared thermometer 64 is activated, lowering the infrared emitting module 641. The camera module 642 is aimed at the point being measured, and the infrared signal is converted by the signal processor 65 and the temperature is displayed. Gas temperature measurement: The gas flow switch is activated, and the gas to be measured flows into the guide groove 633 through the inlet pipe 632. The temperature sensing resistor 634 collects the temperature signal, and the data is processed and displayed. After the temperature measurement is completed, the controller 68 retracts each temperature sensing element, closes the gas flow, removes the object being measured, and cuts off the power.

[0031] This device is based on multi-dimensional adjustment, multi-mode temperature measurement, and data optimization as its core logic. Adjustment logic: By adjusting the horizontal position of the moving mechanism 3, the angle of the deflection mechanism 4, the height of the lifting mechanism 5, and the support height of the supporting mechanism 2, a comprehensive adjustment system is constructed to ensure that the temperature measuring element is accurately aligned with the measured point. Temperature measurement logic: Select the corresponding temperature measuring element according to the characteristics of the object being measured. In contact scenarios, it relies on the resistance change of the platinum resistance thermometer 62 or the temperature sensing resistance 634 signal of the gas thermometer 63. In non-contact scenarios, it relies on the infrared radiation signal of the infrared thermometer 64 to achieve on-demand adaptation. Safety and accuracy assurance logic: Limit sensor 13 and limit sensor 24 prevent horizontal overtravel, pressure sensor 55 avoids excessive contact, signal processor 65 optimizes data error, multiple designs ensure the safety of device operation and temperature measurement accuracy, and finally output reliable temperature measurement results through display 7.
